Abstract
A light guide member for guiding a beam of light from a light emitting element, fixedly mounted on a printed circuit board, towards a display window defined in a casing that encloses the light emitting element and the printed circuit board therein. The light guide member includes a transparent rod having at least first and second reflecting surfaces defined therein at different locations along the length of the transparent rod. The transparent rod is designed to allow the beam of light to travel in three dimensions along the entire length of the transparent rod from a light receiving face, defined at one end of the transparent rod, to a light emitting face defined at the opposite end of the transparent rod.
